I am unable to get my 2018 suburban premier to enter programming mode for they keyfob. I have followed all the tutorials online for programming a new fob with no luck. I only have 1 working keyfob so I have been using those sets of directions. I insert the emergency key into the tumbler, I turn it counter clockwise 5 times and nothing happens. I have tried it with the fob in my hand, I have tried locking the doors first, I have tried it with the door open and closed. I have tried starting the car, turning it off, and then doing it. I have tried it with the car on. I have tried it with the keyfob outside the range of the car with just the emergency key. basically I have tried every variable I can think of that would be causing it to not enter programming mode So I decided to take to to a locksmith to get the fob programmed. The locksmith hooked up their computer to my car and went through the programming process and it didn't work. He tested the key for signal and it was sending signal, we verified I had the right chip inside it and he was stumped. He said maybe the fob I got was bad, but in his career he has only seen that happen once. My worry is that there is something wrong with my suburban. Any help or tips would be greatly appreciated!

You may have the wrong FOB for your vehicle. Just because it looks the same as your current FOB doesn’t mean it’s the right one. The FCC ID needs to match.
 

Your best chance of success, and your sanity, is to take it to the dealer.

I think you might be right. I thought I had matched all that stuff up but I am definitely not an expert. The dealership just wants what seems like an insane amount of money ($400+) to do up a new fob. but that might be my only choice.

Oof, don’t fall for this. It’s a weak attempt at ‘customer support.’
 

The best way of finding the right fob is taking it apart (there are videos online) like you’re replacing thr battery. Incr apart, look for the FCC ID number printed somewhere on the circuit board. It’ll be in very, very small print. Then buy a fob with the same FCC ID number.

Yeah. I agree. I already talked to a dealership and they want over $400 for a new programmed key. I did purchase one that had the right chipset in it with matching FCC ID. For some reason my suburban just won't enter the programming mode. No matter what I try. 😕

You need to go to the dealer.  2017 and onwards you NEED to have 2 already programmed fobs to start with to use the learn procedure you are using.  If you only have ONE original key, the dealer has to to a delete and add programming procedure so you take both keys with you, they will delete the original and then program both back in.  

 

Link below explaining the change made:

 

UPDATE: Quick Learn Procedures for Programming 2017MY Keys and Key Fobs – TechLink (gm-techlink.com)

 

Quote

TIP: If only one learned key is present, SPS must be used to add additional keys. The quick learn procedure will not complete with only one learned key. Using only one key for the quick learn procedure will cause the theft security light to illuminate when attempting to start the vehicle.

Same thing with my Ford. I bought vehicle with only one key, so paid Ford dealer $480 for a second key. Then bought a third key off Amazon and programmed it in myself. Now if I lose a key, I still have two, and can program more.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
